When I began studying medicine here in Germany, we had to do internships with the nurses. It included having to wipe shit of patients bottoms and stay with patients that were vomiting and hold a bowl for them to vomit in.

Let them have a run with combivir. After taking it prophyactically for a needle stick from unknown origin I can guarantee that they will get over their worries pretty damn quick. I do not see a career in ID for them.
